Product description
EKM008 is a very slim power supply, intended for direct use with breadboards. The power supply will span the height of the breadboard and connect to both power rails, providing 3.3V or 5V depending on the switch setting.
The module can be powered either via the USB-C port, using any regular USB power supply, or the adjacent holes marked "IN 3-16V". The auxillary input can also be used as a direct output from the USB-port to supply 5V when the module is set to 3.3V.
The included 2x3-pin headers can be soldered on either side of the board and will provide power to both lengthwise power rails with the same voltage. An additional output with a pitch of 3.5mm is available on the edge and will fit a standard 3.5mm screw terminal or wires soldered directly to the board.
The maximum current consumption is limited by the internal switches in the regulator and depends on the input voltage and the selected output voltage. When powered with 5V from a standard USB adapter, it can deliver approximately 2A. However, the current consumption is somewhat limited during startup. If the start up current is too high, the EKM008 will fail to start. The startup current is limited to approximately 600 mA.
Since the regulator is a switching step-up/step-down regulator, the efficiency is very high (over 90%) and it will happily convert a lower voltage to a higher or a higher to a lower without interruption or glitches.
